Harley Davidson New Worker Women's Black Black Nubuck Biker Boots Shoes

Hello. The sole of the New Worker model is made of nubuck leather, meaning it is made from real leather. While I can't give you exact measurements about the sole length of size 39, you can find detailed measurements in the size chart on the product page. You can choose the right number by comparing your foot length in centimeters with the table. If you have a regular size, you can choose that size; however, due to the nature of nubuck leather, the size that makes your foot feel comfortable is the best.
